I'm having a problem with an otherwise OK-seeming Dunhill Rollagas of ~1970s vintage. It seems to be stainless steel.
I'm having the toughest time keeping the flame consistent. I'll try and explain the facts and my observations.
-The lighter has been bled and filled with the best quality butane I could find on short notice, a British brand called Lucienne which boasts, at least, of "zero impurities."
-The lighter takes gas well and does not seem to leak it, st least not in any observable way.
-A test run with gross and fine gas flow adjusters indicates gas seems to flow through the lighter just fine, too. At least for a while, as you'll see.
-I adjust the gross and fine flame controls to give me a flame the average cigarette smoker would say is reasonable.
Here's where the problem comes in... The flame ALWAYS decreases in height over the course of a few minutes/lights to about four hours. It does this with no inputs or changes to the gross or fine flame adjusters, no matter how I adjust it. Eventually the flame goes down to almost no height at all.
I've tried a little bootleg trick I saw, where you blast the flame nozzle with butane, though I imagine any pressurized gas, like Dust-Off, would do. I get the most time at reasonable flame height that way, but like I said, it always ends up decreasing again.
I'm thinking there may be some dirt in the works somewhere, or possibly the flint is degraded or otherwise cruddy. I just bought it, haven't laid into new Dunhill flints yet. I'd bet a lot it's been serviced in the not-too-distant past, too, precisely because it seems to hold gas.
I'd be grateful for any thoughts, solutions, ot advice anyone could give. If anyone's had a similar problem, they haven't posted online about it that I can see.
Vintage or otherwise from Alfred Dunhill, you'll find it here.
